Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to a mining flameproof and intrinsically safe computer. Background Art

[0002] In the environment of mining operations, the demand for computer equipment is increasing day by day, but traditional computer equipment often has many problems. In the past, the explosion-proof level of computer power supplies was relatively low, making it difficult to meet the requirements of the complex and dangerous environment in mines, which brought potential safety hazards to mining operations.

[0003] In order to avoid dangerous situations, intrinsically safe computers are used. Through a specially designed explosion-proof housing, the internal circuit is isolated from the external explosive environment. Even if faults such as short circuits and sparks occur inside, it will not cause an explosion in the external explosive environment, and the equipment will not generate dangerous signals such as high heat, high voltage, and high frequency during operation, thus avoiding the factors that cause explosions.

[0004] However, the existing intrinsically safe computers are relatively single in terms of assembly integration. Specifically, they cannot integrate and collect the wired, electromagnetic wave, and mud pulse systems in one computer, resulting in the need to equip multiple different types of computers in actual applications. This not only increases costs and operational complexity but also occupies more space. Moreover, the number of explosion-proof interfaces of existing intrinsically safe computers is limited, making it difficult to meet diverse needs, especially lacking an interface for communicating with the drill control box, which greatly limits the information interaction and collaborative work between the computer and the drill.

[0042] Second Embodiment

[0043] Please refer to Figure 5 and Figure 6 Based on a mine explosion-proof and intrinsically safe computer provided by the first embodiment of the present application, the second embodiment of the present application proposes another mine explosion-proof and intrinsically safe computer. The second embodiment is only a preferred manner of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0044] Specifically, the difference of a mine explosion-proof and intrinsically safe computer provided by the second embodiment of the present application is that on the side of the housing 1, a protective frame 4 is fixedly installed, and a plurality of installation grooves 42 are opened on the side of the protective frame 4. At the top of the inner side surfaces of the plurality of installation grooves 42, sliding grooves 41 are opened.

[0045] Slidingly connected to the inner side surfaces of the plurality of sliding grooves 41 are baffles 43. Fixedly installed at the top of the baffles 43 are moving plates 44, and the bottom of the moving plates 44 is disposed on the top of the protective frame 4.

[0049] When in use, when the user needs to plug in the external transmission line and the interface, the user can move the moving plate 44 upward, so that the moving plate 44 drives the baffle 43 to move upward, so that the baffle 43 slides on the inner side surfaces of the chute 41 and the installation groove 42 until it completely moves away from the inner side surface of the installation groove 42. After that, the user can connect the transmission line to the interface arranged on the inner side surface of the installation groove 42.
